    • Development of a Pavement Rutting Model from Experimental Data 

      Adrián Ricardo Archilla; Samer Madanat (American Society of Civil Engineers, 2000)
      Properly specified pavement deterioration models are an important input for the efficient management of pavements, the allocation of cost responsibilities to various vehicle classes for their use of the highway system, and ...
    • Aerodynamics of Electrically Driven Freight Pipeline System 

      Thomas S. Lundgren; Yiyuan Zhao (American Society of Civil Engineers, 2000)
      This paper examines the aerodynamic characteristics of a freight pipeline system in which freight capsules are individually propelled by electrical motors. The fundamental difference between this system and the more ...
    • Design and Analysis System for Thermal Cracking in Asphalt Concrete 

      Amy Epps (American Society of Civil Engineers, 2000)
      A reliability based mix design and analysis system for thermal cracking in asphalt concrete pavements is described and demonstrated in this paper. Asphalt-aggregate mixture performance in terms of low temperature cracking ...
    • SP Approach toward Driver Comprehension of Message Formats on VMS 

      Ka-hung Lai; Wing-gun Wong (American Society of Civil Engineers, 2000)
      This study attempts to examine driver comprehension of the traffic information that is presented in three formats, namely, the numerical format, the description format, and the switch-on-light format. A stated preference ...
    • Ground-Penetrating Radar for Network-Level Concrete Deck Repair Management 

      Christopher L. Barnes; Jean-François Trottier (American Society of Civil Engineers, 2000)
